#13405: kernel panic on atheros AR9230 chip (ATH9K module)
-----------------------+----------------------------------
Reporter: dony74@… | Owner: developers
Type: defect | Status: new
Priority: high | Milestone: Chaos Calmer (trunk)
Component: kernel | Version: 10.03.1
Resolution: | Keywords:
-----------------------+----------------------------------
Comment (by cmtsij):
This is reproducible with curren trunk.
I tested it on r43793 without those two patches with device XWR100.
(support XWR100 with this patch
https://github.com/cmtsij/openwrt/commit/b8f722)
Here is full kernel log:
